GE 139-H-FLC Full Load Current Output Option Relay

The Full Current Output Option Relay 139-H-FLC is a horizontal mounting specialty model.

This model has an external reset switch that works in conjunction with the front panel reset switch.

This model also has an emergency restart option.

Product Description

Model 139-H-FLC is a full load current horizontal mount motor protection relay.

This model has a full load current of 4 to 20 milliamps. Associated protections listed for this relay include overheating, stall-mechanical blocking,

Rotor Lockout, Undercurrent, Ground Fault, Single Phase/Unbalance, Repeat Start, and Overload Protection with selectable curves.

This relay will protect three-phase AC motors from environmental influences that can cause damage.

The 139-H-FLC relay will be used in six applications; one of the applications is to ensure user safety.

This application will utilize the ground fault function to find leakage currents caused by moisture or potential winding shorts in mines, thus preventing shock hazards.

As mentioned above, the relay will be mounted horizontally; it should be noted that a rectangular panel cutout is required for whichever mounting orientation is chosen for the relay.

Once the current breaker is available, the relay will be held in place by two U-clips and then prepared for wiring.

The 139-H-FLC relay can be supplied with ground fault current and it will accept all current carrying conductors through the ground fault current window.

Please note that it is highly recommended that at least two current leads need to be wound together to minimize noise pickup on the relay.

There is a specially designed current that can be used to help output lower level signals.

Frequently Asked Questions about the 139-H-FLC

What is the memory capability of the 139-H-FLC multi-wire general purpose motor protection relay?

This 139-H-FLC is designed to electronically record up to 30 minutes of memory to simulate heat buildup in a motor.

If no overload occurs during this 30 minute period, the memory will be refreshed.

However, if an overload occurs or the motor starts, the circuitry remembers these conditions and can reduce the amount of time available for future overload conditions.

If the motor enters a trip condition due to overheating, the relay will latch to restart for at least 30 minutes to allow the motor to cool.

Motor start trip conditions and overload conditions may cause the motor to heat up, hence the 30 minute lockout time.

Blocked-Rapid Trip, Short Circuit, Unbalance, or Ground Fault conditions do not cause heating and enable the turntable to perform an immediate system reset.

Can users customize the 139-H-FLC Multi-Wire Universal Motor Protection Relay for specific motors?

Users can select from 15 different operating profiles for the 139-H-FLC Multi-Wire Universal Motor Protection Relay.

Four switches are used to select the desired operating profile. The user can find the manufacturer's data for the motor

Plot the data on the run curve to customize the 139-H-FLC to the motor that needs to be protected.

The full load current from terminals one and two on this model will be proportional to the percentage of full motor current.

Current levels will not be affected by any different wiring lengths.
